Abstract
Disclosed is an overcharge detection method for detecting an overcharging of an accumulator of a battery including a set of parallel branches each including accumulators disposed in series, wherein the method includes steps of: (i) collecting the measurements of the currents flowing in the branches of the battery; (ii) identifying at least one variation in current in one branch with respect to at least one other branch as a function of the measurements of current collected; (iii) determining a level of state of charge of the branch; and (iv) detecting an overcharging of an accumulator in the branch as a function of at least the variation in current identified and of the level of state of charge determined.

An overcharge detection method for detecting an overcharging of an accumulator of a battery comprising a set of parallel branches, each branch comprising accumulators disposed in series, wherein the said method includes the following steps:
- (i) collecting the measurements of the currents flowing through the branches of the battery;
- (ii) identifying at least one variation in current in one branch of the said set of branches with respect to at least one other branch of the said set of branches as a function of the measurements of current collected;
- (iii) determining a level of state of charge of the said branch;
- and
- (iv) detecting an overcharging of an accumulator in the said branch as a function of at least the said variation in current identified and of the level of state of charge determined.
An overcharge detection device (1) for detecting an overcharging of an accumulator of a battery comprising a set of parallel branches, each branch comprising accumulators disposed in series, wherein the said device is suitable for and capable of collecting the measurements of the currents flowing through the branches of the battery;
- of identifying at least one variation in current in one branch of the said set of branches with respect to at least one other branch of the said set of branches as a function of the measurements of current collected;
- of determining a level of state of charge of the said branch;
- and of detecting an overcharging of an accumulator in the said branch as a function of at least the said variation in current identified and of the level of state of charge determined.
